No. 422,988 Claims. (Cl. 214-317) This application is a division of application Serial No. 54,541 filed Sept. 7, 1960, now Patent No. 3,164,406.

This invention relates to a container transfer device especially suited for mounting on a vehicle for transferring containers to and from the vehicle horizontally.

It is an object to provide a simple and dependable transfer device which can automatically engage and disengage the load and which is easy to align with the load without manually guiding or hooking hooks.

This invention comprehends a crane or derrick having a telescoping and lifting jib for mounting on a vehicle for transfer of containers to and from the vehicle, the jib being operable to extend from within the vehicle area horizontally out and down to engage the load and up and in to transfer the load onto the vehicle and vice versa to unload the vehicle. By providing the jib with these movements and having the engaging means directly mounted or integral on the jib extension or carrier (instead of providing a hoist on the jib, as is usual practice) the load can be easily aligned automatically and swinging and sway substantially reduced or eliminated.

It is a further object to provide a double jib for engaging opposite sides or ends of the container for greater rigidity in handling containers and a carrier for riding the jibs and telescoping thereon to extend beyond the mounting section of the jibs. It is a further object that the double jib straddle the container to reduce the overall height, and further to extend to place a plurality of containers on the vehicle. Other features such as using the jib to tilt the container to empty it are also provided for.

Still other or further objects will be pointed out hereinafter or should be apparent from consideration of this invention as described with reference to the accompanying drawings wherein:

FIGURE 1 is a perspective view of a truck mounted container loader about to pick up a container.

FIGURE 2 is a side elevation of the rear portion of the loader with a portion cut away to show the interior of the dashpot and shown dumping a load.

FIGURE 3 is a partial perspective and schematic view of the controls for the loader.

FIGURE 4 is a plan view of the loader.

Referring to the drawings, a truck mounted derrick 240, FIGURES 1-4 can be provided to engage and disengage containers 242 automatically and lift on or set off one or more of them on the truck with my hooks 10c.

Container 242 is preferably of the now common type having two trunnions 243 on opposite ends near the top. Hooks 10c each have a lower cam 18 to latch over the trunnions when let down thereon. The lower cams of the hooks are preferably bent out at the bottom to engage the container better. The hooks are mounted to swing on or with shaft 244 secured between parallel outturned channels 246 which are spaced apart and connected by a channel section 248 to form a carrier 250. The hooks swing to vertical position by gravity and have an upper cam 30 which engages the trunnion to swing the hook wide open when the load is set down and the derrick is lowered further. A dashpot 32 delays the closing of both hooks if they are secured to turn with shaft 244, but it is preferred to have the hooks turn on the shaft to latch independently of each other, and accordingly each hook has a dashpot 32 or its equal to delay the closing of hooks only after opening wide until the derrick can lift the hooks above the load. The dashpot is clevis mounted between the hook and carrier 250 as shown in FIGURE 2 and is further described in my Patent Number 3,164,406, issued January 5, 1965.

Carrier 250 is supported on a boom 252, which comprises two parallel channels 254 spaced to straddle container 242 and pivotally secured on the same axis facing out, one on each side and near the top of an A-frame 256, which is secured on the truck bed 258 near the front. Bar 260 at the rear above channels 254 spaces them. Wheels or rollers 262 are spaced and secured along the facing faces of channels 254 to run in channels 246 and support the carrier. A cylinder 264 is clevis mounted to a yoke 266 connecting channels 254 on the under side thereof near A-frame 256. Yoke 266 is bent up in the center to permit use of a longer cylinder 264 without cutting away the truck bed to increase the lift of the derrick. Yoke 266 is therefore pivotally secured below each channel 254.

A cable 268 is anchored to the forward end of carrier 250 at 270 and is run back around pulley 272 on the extended end of the channel 254 on the same side of the truck. The cable runs from there over a pulley 274 on the pivot end of the boom and down around a drum 276. Another cable 268' or a continuation of the first is run forward from the anchor 270 over a pulley 276 on the same pin as pulley 274 and down around drum 276 in the opposite direction so that the drum reels on and off opposite ends of the cable as it turns and runs the carrier in or out on the boom according to the direction of rotation of drum 276. Drum 276 can be turned and held by a hand winch or preferably by motor 280 through worm reducer 282 whose worm gear is secured on shaft 284 for turning drum 276. Motor 280 is preferably operated from the truck battery 286 by connection across the battery through reverse switch 288, shown in FIG- URE 1. A similar cable arrangement is preferably provided on the opposite side of the truck and driven from the same shaft to reduce the possibility of the carrier twisting and to take part of the load. Boom 250 preferably extends to the edge of the truck frame or bed and carrier 250 extends out beyond the end of the boom as shown in FIGURES 1, 2, and 4, to pick up, set down and dump containers 242. Carrier 250 is therefore considered to be the telescoping end of the double boom 252.

Container 242 has runners 290 secured on the bottom to engage a rim 292 across the rear of the truck bed for dumping the box as shown in FIGURE 2.

Having thus described one of the many possible embodiments and applications of this invention, it should be understood that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense, further I contemplate to cover by the appended claims all variations and parts which fall within the true spirit and scope of this invention.
